Creating Date Field: Temporary Error

I created a new field called “Date” – short name “date” http://ee400.dev/admin.php?/cp/fields/create

Submitted the form and it reported that was a reserved name.

Changed the short name to “date_field” and resubmitted

The form flashed an error message about “duplicate field name” for a second or two, and then it submitted correctly.

Not a huge problem, but something to investigate?
